さくらレンタルサーバーで ruby 3.3.0 をビルド

Last updated at Posted at 2023-12-29

はじめに

さて,クリスマスといえばRubyのメジャーアップデートですね.早速 去年と同じ方法 で ruby 3.3.0 をインストールしてみましょう.

==> Installing ruby-3.3.0...
-> ./configure "--prefix=$HOME/.rbenv/versions/3.3.0" --enable-shared --with-ext=openssl,psych,+ --disable-install-rdoc --with-openssl-dir=/usr/local "--with-libyaml-dir=$HOME/local"
-> make -j 8

BUILD FAILED (FreeBSD 13.0 on amd64 using ruby-build 20231225-2-g3b79c293)

You can inspect the build directory at /home/cycloawaodorin/tmp/ruby-build.20231229170435.10771.KdS07E
See the full build log at /home/cycloawaodorin/tmp/ruby-build.20231229170435.10771.log

おや,ビルドに失敗してしまいました.ログを見てみましょう.

???
何が原因でしょうか.よくわかりません.

原因

新しいバージョンのGCCを試してみようとビルドを試みたものの,こちらのビルドも失敗.ググって見たところ,あるフォーラム議論 が見つかりました.

xg++: fatal error: Killed signal terminated program cc1plus
In almost every cases, this means ran out of memory

ああ,これはありえそうです.さほどメモリが潤沢ではないのに,make -j 8は厳しいかもしれません.

解決法

次の環境変数を設定すればビルドできます.

MAKEOPTS="-j1"

他の環境変数と合わせると,実行すべきコマンドは

$ CC=gcc MAKEOPTS="-j1" RUBY_CONFIGURE_OPTS="--with-openssl-dir=/usr/local --with-libyaml-dir=$HOME/local" TMPDIR="$HOME/tmp" rbenv install 3.3.0

となります.libyaml-devは 前回の記事 の方法でビルドしておきましょう.

==> Installing ruby-3.3.0...
-> ./configure "--prefix=$HOME/.rbenv/versions/3.3.0" --enable-shared --with-ext=openssl,psych,+ --disable-install-rdoc --with-openssl-dir=/usr/local "--with-libyaml-dir=$HOME/local"
-> make -j1
-> make install
==> Installed ruby-3.3.0 to /home/cycloawaodorin/.rbenv/versions/3.3.0

無事ビルドできました.

というわけで,makeを8並列実行してはメモリ不足でビルドに失敗するので,並列実行をやめましょうということでした.

ちなみに GCC 13.2 は MAKEOPTS="-j1" でもビルドに失敗したので,使いたい場合はローカルマシンでクロスコンパイルしてアップロードする必要がありそうです.

追記

Killed
*** [ext/digest/exts.mk] Error code 137

どうやら137というのがメモリ不足のしるしみたいですね."Killed"というのもメモリー使い切りで発生させたことがあった気がします.
